Rhythm is the first to produce and market a 2-piece aluminum integrated BMX crankset! The crank and spindle are integrated together meaning the bottom bracket spindle is permanently attached to the drive side crank arm. The external bottom bracket bearings mount outside the bottom bracket shell allowing the use of bigger more durable bearings. Here are the specs and details about this crank:
